Description

Technical Field

[0001] This utility model relates to a milling cutter for machining mechanical parts, specifically a wear-resistant milling cutter for machining mechanical parts, belonging to the field of mechanical parts machining technology. Background Technology

[0002] With the rapid development of social production and technology, mechanical products and their parts are becoming increasingly precise and complex. Therefore, various machining equipment is used to process these parts. Among them, milling machines are a common type of machining equipment and are widely used in mechanical manufacturing and repair departments. Under normal circumstances, these parts are processed by milling cutters on milling machines.

[0003] In the prior art, such as the novel combined clamped milling cutter for machining mechanical parts disclosed in announcement number CN216858361U, the first fixing bolt is first rotated out using a tool. Then, by holding the cutter head and using the extension and retraction of the connecting column in the main sleeve, the distance between the cutter head and the cutting edge can be adjusted. After the distance is adjusted to a suitable size, the hole opened inside the main sleeve is aligned with the corresponding mounting hole. Then, the first fixing bolt is screwed into the aligned hole to complete the adjustment of the cutter head position. Finally, by using the connection between the cutter head and the collet, the milling cutter can be installed below the machining equipment.

[0004] However, in implementing the relevant technology, the above-mentioned design of a novel modular clamping milling cutter for machining mechanical parts has the following problems: In the prior art, the milling cutter can be disassembled and assembled through the cooperation of components such as the first fixing bolt. However, in actual use, since mechanical parts are not only made of conventional metal materials, but also some of them are made of extremely hard materials, the milling cutter wears out too much and has a short lifespan during use. In view of this, a wear-resistant milling cutter for machining mechanical parts is provided to overcome the above defects. Utility Model Content

[0005] This invention addresses the problem of excessive wear and short lifespan of milling cutters during use, which arises because mechanical parts are not only made of conventional metals but also of materials with extremely high hardness. Therefore, this invention provides a wear-resistant milling cutter for machining mechanical parts.

[0006] The present invention achieves the above objectives through the following technical solution: a wear-resistant milling cutter for machining mechanical parts, comprising a cutter bar, a cutter head fixed at the bottom end of the cutter bar, and a liquid supply mechanism sleeved on the outside of the cutter bar;

[0007] The liquid supply mechanism includes a rotating housing, which is rotatably connected to the outer wall of the cutter bar. A rotating hole is provided inside the rotating housing corresponding to the position of the cutter bar. A limit ring is fixed on the inner wall of the rotating hole, and a flow hole is provided on the outer wall of the cutter bar facing the limit ring. A limit groove is provided on the cutter bar corresponding to the position of the rotating hole, and a feed hole is provided on the inner wall of the limit groove. A discharge hole is provided on the lower part of the outer wall of the cutter head.

[0008] Preferably, the limiting ring and the tool holder form a rotating structure, and the tool holder and the limiting ring are in close contact.

[0009] Preferably, the flow hole communicates with the feed hole, and the feed hole communicates with the discharge hole.

[0010] Preferably, a sleeve extends through one side of the outer wall of the rotating shell, and an infusion tube extends through the inside of the sleeve.

[0011] Preferably, the top of the rotating shell is provided with an abutting mechanism, which includes a connecting cylinder, the connecting cylinder being fixed to the top of the rotating shell, and a protruding rod extending from the inside of the connecting cylinder, with an abutting block fixed to the top of the protruding rod.

[0012] Preferably, the abutment mechanism further includes a limiting block, which is fixed to one end of the through rod that enters the connecting cylinder, and a spring is connected below the limiting block.

[0013] Preferably, the limiting block forms an elastic structure with the spring and the connecting cylinder, and the connecting cylinder and the through rod form a sliding structure.

[0014] The beneficial effects of this utility model are as follows: The rotating shell and the tool holder are rotatably connected via the rotating hole and the limiting groove. Simultaneously, the limiting ring adheres to the tool holder, facilitating communication between the flow hole and the feed hole during tool holder rotation. This allows coolant to enter and flow out through the discharge hole, providing lubrication and heat dissipation during milling, preventing excessive friction and wear. One end of the sleeve is threaded to the rotating shell, and the other end is threaded to the fluid supply pipe, facilitating quick and easy assembly and disassembly for coolant supply. The rotating shell also limits rotation, preventing it from following the tool holder and improving stability. Furthermore, the spring inside the connecting cylinder pushes the through-rod, supporting the limiting block against the chuck or power end of the milling cutter, providing stability and preventing wobbling with the tool holder. The limiting block also prevents the through-rod from over-extruding and becoming loose. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1, as Figures 1 to 5 As shown, an anti-wear milling cutter for machining mechanical parts includes a cutter shank 1, a cutter head 2 fixed to the bottom end of the cutter shank 1, and a fluid supply mechanism 3 sleeved on the outside of the cutter shank 1. The fluid supply mechanism 3 includes a rotating shell 301, which is rotatably connected to the outer wall of the cutter shank 1. A rotating hole 302 is opened inside the rotating shell 301 corresponding to the position of the cutter shank 1. A limiting ring 303 is fixed to the inner wall of the rotating hole 302. A flow hole 304 is opened on the limiting ring 303 facing the outer wall of the cutter shank 1. A limiting groove 305 is opened on the cutter shank 1 corresponding to the position of the rotating hole 302. A feed hole 306 is opened on the inner wall of the limiting groove 305. A discharge hole 307 is opened below the outer wall of the cutter head 2. The limiting ring 303 and the cutter shank 1 form a rotating structure. The cutter shank 1 and the limiting ring 303 are tightly fitted together. 04 is connected to the feed hole 306, which is connected to the discharge hole 307. A sleeve 4 extends through one side of the outer wall of the rotating shell 301, and a liquid delivery pipe 5 extends through the inside of the sleeve 4. Through the rotating hole 302 and the limiting groove 305, the rotating shell 301 is rotatably connected to the tool holder 1. At the same time, the limiting ring 303 fits against the tool holder 1, so that the flow hole 304 and the feed hole 306 can communicate when the tool holder 1 rotates, allowing the coolant to enter and flow out through the discharge hole 307. This provides lubrication and heat dissipation during milling, avoids excessive friction, and prevents wear. One end of the sleeve 4 is threaded to the rotating shell 301, and the other end is threaded to the liquid delivery pipe 5, which facilitates quick disassembly and assembly and supplies coolant. At the same time, the rotating shell 301 is limited to prevent it from rotating with the tool holder 1, thus improving stability.

[0023] Example 2: In addition to all the technical features in Example 1, this example also includes: a contact mechanism 6 is provided at the top of the rotating shell 301. The contact mechanism 6 includes a connecting cylinder 601, which is fixed to the top of the rotating shell 301. A protruding rod 602 extends through the inside of the connecting cylinder 601, and a contact block 603 is fixed at the top of the protruding rod 602. The contact mechanism 6 also includes a limiting block 605, which is fixed at the end of the protruding rod 602 that enters the connecting cylinder 601. A spring 604 is connected below 05. The limiting block 605 forms an elastic structure with the connecting cylinder 601 through the spring 604. The connecting cylinder 601 forms a sliding structure with the through rod 602. The spring 604 inside the connecting cylinder 601 pushes the through rod 602 to support the limiting block 605 and abut against the chuck or power end of the milling cutter, which has a stabilizing effect and prevents it from shaking with the tool holder 1. At the same time, the limiting block 605 prevents the through rod 602 from going out too far and causing loosening.

[0024] The rotating housing 301 rotates with the tool holder 1 through the rotating hole 302 and the limiting groove 305. At the same time, it is attached to the tool holder 1 through the limiting ring 303, which facilitates the coolant to enter the feed hole 306 through the flow hole 304, and then flow out through the discharge hole 307 after passing through the internal channel. This provides lubrication and heat dissipation, avoids excessive friction during turning, and has an anti-wear effect. The liquid supply pipe 5 is connected to the external coolant supply equipment and is threaded to the liquid supply pipe 5 through the sleeve 4 to adjust its position, thereby inserting it into the rotating housing 301 for feeding. The rotating housing 301 remains stationary while the tool holder 1 drives the tool head 2 to rotate normally. The spring 604 embedded in the connecting sleeve 601 elastically pushes the through rod 602. The limiting block 605 prevents the through rod 602 from over-extruding. The through rod 602 abuts against the machine tool power head or chuck through the abutment block 603 to improve the stability of the rotating housing 301.
